Darby Translation

³ And he had seven hundred wives, princesses, and three hundred concubines; and his wives turned away his heart.

⁴ And it came to pass when Solomon was old, [that] his wives turned away his heart after other gods; and his heart was not perfect with Jehovah his God, as the heart of David his father.

⁵ And Solomon went after Ashtoreth the goddess of the Zidonians, and after Milcom the abomination of the Ammonites.
